/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57301.161308 0.001365 0.25994 0.06550 0.98936 1 0.67011 0.07774 0.33201 0.03850 0.17419 0.03896 0.08602 0.01924 57301.165709 0.003036 0.15080 0.03132 0.98887 1 0.69127 0.05268 0.34454 0.02625 0.10424 0.02014 0.05206 0.01006 57301.222182 0.001133 0.38062 0.10054 0.98718 1 0.42228 0.05929 0.27514 0.03861 0.16073 0.03596 0.10390 0.02323 57301.224695 0.001380 0.30804 0.07873 0.96842 1 0.43958 0.05439 0.28259 0.03495 0.13541 0.03028 0.08696 0.01944 57301.228980 0.002905 0.18630 0.04079 0.98500 1 0.42946 0.03735 0.27082 0.02354 0.08001 0.01608 0.05056 0.01015
